Subject: ISS Predictions

Following is a recent report of the International Space Station that I
made. ISS can easily be seen without aid if the weather permits. Sites
on the internet for getting orbital elements include
https://www.space-track.org (very current data from the Department of
Defense), http://celestrak.com (maintained by COL TS Kelso) and
https://www.mmccants.org (maintained by Mike McCants). The last site
contains satellite elements of classified objects.
